In January–April 2010, U.S. Army intelligence analyst Chelsea Manning used access to the military’s digitized classified networks, including SIPRNet and JWICS, to copy and transmit nearly 750,000 military reports, diplomatic cables, and videos to WikiLeaks. The material included about 400,000 Iraq War Logs, 91,000 Afghanistan-related reports, 251,287 diplomatic cables, and footage of the 2007 Baghdad airstrike. Manning reportedly bypassed controls by copying files to removable media disguised as a Lady Gaga CD, illustrating how broad database access and portable storage created a major information-security vulnerability.
The Army had discussed whether Manning was a risk before deploying her and witnesses believed her access should have been withdrawn after a December 2009 workplace incident, but she remained able to access sensitive systems. After her May 2010 arrest, she was held under restrictive prevention-of-injury conditions at Quantico, prompting domestic and international criticism. A court-martial convicted her in July 2013 on 17 charges and amended versions of four others, but acquitted her of aiding the enemy; she received 35 years. President Barack Obama commuted the sentence on January 17, 2017, after nearly seven years in confinement. Manning later spent March 2019–March 2020 jailed for contempt and was fined $256,000 for refusing to testify before a grand jury investigating WikiLeaks founder Julian Assange.
